Features

1, manual part can use steel plate restraint handle or stainless steel casting handle. The handle is provided with a limiting structure, and the limit is set at the position of the valve opening and closing. When the valve is used on the key assembly, a lock hole is arranged on the limit block, and the switch position can be locked to avoid misoperation. There are marked on and off signs on the handle.
2, stem using A182F (1Cr13) group forging and modulation treatment, hardness of HB220 ~ 250. The valve stem is connected with the handle by the flat key or spline or square, and the utility model has strong versatility and convenient disassembly and assembly. The valve stem is provided with blowout proof structure.
3, the valve selection of filler knitting, flexible graphite sealing ring or PTFE graphene sealing ring, allowing stem to realize the reliable sealing in lubrication under certain.
4, according to the necessary, ball valve can be designed to prevent static structure, in the ball and stem, stem and valve body between the conductive spring, to avoid static ignition, ignite flammable substances, to ensure system safety.
5, the sealing pairs vary. According to the different working conditions, soft sealing, hard sealing and fireproof valve seat can be used; DN150 is the floating ball situation, and DN200 is the fixed ball situation.
6, ball valve seat can be set up auxiliary sealing structure, in the seat and stem parts with grease injection valve, in case of emergency can be temporarily sealed, and can be lengthened according to the necessary stem, suitable for underground paved place
